Description

Technical Field

[0001] The utility model relates to an air conditioning system for a kitchen. Background Art

[0002] Stuffy, humid, and odor have always been the pain points of kitchen use. In addition to the ambient temperature, the reasons for the stuffy problem are that the kitchen range hood has a large air volume and requires a large amount of supplementary air; gas combustion and human consumption, lack of oxygen in the kitchen, and excessive combustion exhaust gas can also cause the kitchen to be stuffy. In the prior art, the problem of kitchen stuffiness is solved by installing air conditioners in the kitchen, opening windows for ventilation, and the problem of air quality in the kitchen is solved by ventilation of range hoods. The use of air conditioners has problems such as oil fume pollution and low frequency of use. Opening windows for ventilation cannot fundamentally solve the problem of air supplementation of range hoods. For example, on rainy days, smog days, hot summers, and cold winters, it is basically impossible to open windows, and the problem of air supplementation cannot be solved. The solution to poor kitchen air quality is only one-way ventilation of the range hood, but the gas extracted is not supplemented, and the kitchen is still in a negative pressure state. It is either supplemented from other rooms such as the living room, or supplemented from outside the window, but the gas outside the window has not been purified, it is not fresh air, and may contain a large amount of PM2.5 or CO2.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the kitchen air conditioning system in this embodiment is arranged in the kitchen. The kitchen air conditioning system comprises a housing 1 , a first air conditioning module 2 , and a second air conditioning module 3 .

[0030] The housing 1 has a first air passage 11 and a second air passage 12 which are isolated from each other. Specifically, a partition is provided in the housing 1 to isolate the space in the housing 1 into two independent spaces, thereby forming a first air passage 11 and a second air passage 12. Both the first air passage 11 and the second air passage 12 have an inlet and an outlet, thereby allowing airflow to flow. The inlet and outlet of the first air passage 11 are both connected to the external environment, the inlet of the second air passage 12 is connected to the external environment, and the outlet of the second air passage 12 is connected to the kitchen space.

[0031] Specifically, the inlet of the first air channel 11 is connected to the external environment through the first tube body 5, and the inlet of the second air channel 12 is connected to the external environment through the second tube body 6. A first valve body 51 capable of opening and closing the first tube body 5 is provided in the first tube body 5, and a second valve body 61 capable of opening and closing the second tube body 6 is provided in the second tube body 6. In this way, the opening and closing of the inlets of the first air channel 11 and the second air channel 12 can be controlled by controlling the opening and closing of the first valve body 51 and the second valve body 61. When the first valve body 51 and the second valve body 61 are opened, the first air channel 11 and the second air channel 12 can introduce air from the external environment.

[0032] The first air conditioning module 2 is arranged in the first air passage 11, and the second air conditioning module 3 is arranged in the second air passage 12. The first air conditioning module 2 is used to achieve heat dissipation and exhaust, and the second air conditioning module 3 is used to supply air to the kitchen. In this embodiment, the first air conditioning module 2 and the second air conditioning module 3 use air conditioning components in the prior art, and then work according to the working principle of air conditioning in the prior art. At the same time, some non-air conditioning components are additionally arranged according to the requirements of fresh air demand, air outlet temperature, etc.

[0033] Specifically, the first air conditioning module 2 includes a compressor 21, a condenser 22, and a first fan 23 connected in sequence. The air outlet of the first fan 23 is connected to the outlet of the first air channel 11, and then under the action of the first fan 23, the first air channel 11 can be used to complete the work of exhausting air and dissipating heat. The second air conditioning module 3 includes a second fan 31 and an evaporator 32 connected in sequence. When all components in the first air conditioning module 2 and the second air conditioning module 3 work in coordination, the temperature adjustment effect can be achieved, and the wind of the required temperature can be output to the kitchen space. Since the first air channel 11 and the second air channel 12 both introduce wind from the external environment, the fresh air ventilation effect is achieved on the basis of adjusting the temperature in the kitchen space. When only the first fan 23 in the first air conditioning module 2 works, the exhaust or heat dissipation effect is exerted accordingly, and when only the second fan 31 in the second air conditioning module 3 works, the fresh air introduction effect is only exerted accordingly.

[0034] However, in order to ensure the cleanliness of the fresh air introduced into the kitchen space through the second air passage 12, the second air conditioning in this embodiment also includes an air purification component 33, which is arranged at the inlet of the second air passage 12. The air purification component 33 purifies the air input from the outside to ensure the cleanliness of the introduced fresh air. At the same time, based on the setting position of the air purification component 33, the air entering from the outside environment can be purified at the first time, so that the airflow processed by the second air conditioning module 3 is also the purified fresh air flow, and then cleaner air can be output to the kitchen space. The air purification component 33 can adopt various purification structures that can filter and purify the air in the prior art.

[0035] In addition, the second air conditioning module 3 in this embodiment further includes an air heater 34, which can heat the fresh air introduced into the second air passage 12 to avoid a large temperature difference between the output fresh air and the air in the kitchen space and thus affect the temperature in the kitchen space. In particular, in winter, the temperature stability in the kitchen space can be effectively ensured.

[0036] In this embodiment, the second fan 31 is arranged at the inlet of the second air channel 12, and the outlet of the second fan 31 faces the inlet of the second air channel 12. The outlet of the second fan 31 is connected to the inlet of the evaporator 32 and the air heater 34 through the three-way pipe 35. The outlet of the second air channel 12 includes an air conditioning air outlet 121, and the outlet of the evaporator 32 is connected to the air conditioning air outlet 121. The outlet of the second air channel 12 includes a fresh air outlet 122, and the outlet of the air heater 34 is connected to the fresh air outlet 122. In order to effectively control the switch of the air conditioning air outlet and the fresh air outlet 122, in this embodiment, a third valve body 351 that can adjust the connection between the second fan 31 and the evaporator 32 or the air heater 34 is set in the three-way pipe 35. By adjusting the third valve body 351, the outlet of the second fan 31 can be connected only to the air heater 34, and then only fresh air is output; or the outlet of the second fan 31 is connected to both the air heater 34 and the evaporator 32, and then fresh air and air conditioning air are output at the same time.

[0037] The housing 1 is also provided with a return air port 4, which is switched on and off with the first air channel 11 and the second air channel 12. Specifically, the return air port 4 is located in the air outlet space and is arranged at the intersection of the first air channel 11 and the second air channel 12. The return air port 4 is provided with a fourth valve body 41 which can conduct the first air channel 11, conduct the second air channel 12 or close the return air port 4. Based on the control of the fourth valve body 41, when the return air port 4 is opened and the return air port 4 is connected to the first air channel 11, the dirty gas in the kitchen space can be discharged out of the first air channel 11 on the basis of the operation of the first fan 23. The wind assembly 7 includes a frame 71 with an air outlet and a fan blade 72 connected to the frame 71 in rotation corresponding to the air outlet. When the return air port 4 is connected to the second air channel 12, the air flow in the kitchen space will be circulated on the basis of the operation of the second air conditioning module 3, which can reduce energy consumption especially in summer.

[0038] In addition, in order to facilitate the air conditioning outlet and the fresh air outlet 122 to be output to the kitchen space more evenly, more conveniently and in the required direction, the kitchen air conditioning system can also additionally be provided with an air outlet component 7 connected to the air conditioning outlet and the fresh air outlet 122. The air outlet component 7 includes a frame 71 with an air outlet and a fan blade 72 rotatably connected to the frame 71 corresponding to the air outlet.

[0039] A range hood is usually provided in the kitchen space to meet the smoke extraction work during cooking. The kitchen air conditioning system can be independently set in the kitchen space, such as being embedded in the top of the kitchen, exposing the air outlet component 7 to discharge air into the kitchen space. The kitchen air conditioning system is embedded in the range hood. In order to facilitate the intelligent linkage with the range hood, the kitchen air conditioning system is also provided with a wireless communication module connected to the controller electrical signal, and then communicates with the range hood through the wireless communication module to coordinate the work.

[0040] The kitchen air conditioning system can adopt different working modes based on different application scenarios. The kitchen air conditioning system in this embodiment can realize the first working mode, the second working mode, the third working mode, the fourth working mode, the fifth working mode, and the sixth working mode.
